  1. 6. Fine and ultrafine particle exposure: Health effects and biomarkers

    Författare :Yiyi Xu; Avdelningen för arbets- och miljömedicin; []
    Nyckelord :particulate matter; Occupational Exposure : adverse effects; mitochondrial dna; telomere length;

    Sammanfattning : Particle, especially fine and ultrafine particle exposure has been linked to lower airway infections, asthma, chronic obstructive pulmonary disease (COPD), ischemic heart disease, stroke and cancer. The underlying mechanisms are under active investigation, and are still not fully understood. LÄS MER

  3. 7. Health-related aerosol particle studies, respiratory tract deposition and indoor source identification

    Författare :Jakob Löndahl; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aerosol particle; health; ultrafine particles; nanoparticle; deposition; respiratory tract; Fysicumarkivet A:000;

    Sammanfattning : Aerosol particles have, since Classical Antiquity, been linked to adverse effects on human health. It is estimated that the particles in urban air pollution causes 100 000 deaths in Europe each year, whereof 5 000 in Sweden. LÄS MER

  4. 8. Elemental composition of fine particles: exposure in the general population and influence from different sources

    Författare :Peter Molnár; Göteborgs universitet; []
    Nyckelord :particulate matter; PM2.5; PM1; ultrafine particles; trace elements; personal exposure; X-ray fluorescence XRF ; indoor levels; air mass back trajectories; long-range transport; domestic wood burning;

    Sammanfattning : The general population is exposed to particulate air pollution from many different local and regional sources. Examples of local sources are traffic, biomass burning and resuspended dust, while regional sources are dominated by combustion processes from heating, traffic and industries. LÄS MER

  5. 9. Aerosol characterization in real life and a methodology for human exposure studies in controlled chamber settings

    Författare :Christina Isaxon; NanoLund: Centre for Nanoscience; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aerosol; human exposure study; exposure; emission; ultrafine particles; aerosol generation; aerosol characterization; candle; terpene; welding; CNT; indoor;

    Sammanfattning : Airborne particles are everywhere around us, and have always been. Particles generated by human activities has increased drastically since industrialization, and several epidemiological studies have shown that inhaled particles can cause adverse health effects. LÄS MER

  7. 10. Experimental Determination of the Deposition of Aerosol Particles in the Human Respiratory Tract

    Författare :Jakob Löndahl; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nanoparticles; deposition; respiratory tract; health; air pollution; aerosol particle; ultrafine particles; lung; Fysicumarkivet A:000;

    Sammanfattning : BACKGROUND: Aerosol particles have, since the antiquity, been linked to adverse effects on human health. It is estimated that the particles in urban air pollution cause at least 100,000 deaths in Europe each year, whereof 5,000 in Sweden. LÄS MER
